You are on the right track. But the curly braces are just a way of telling python its a placeholder for something else.

    age=25
    days=age*52*7
    summary="l am {} old!"

To replace the braces with the variable you want. You will use the .format() built-in function for strings. Use it at the end and inside the parenthesis of format is where you pass the variable you want to substitute in for the curly braces.

So your code should look something like this.

    age=25
    days=age*52*7
    summary="I am {} old!".format(#HINT: A VARIABLE GOES HERE)
